How to adjust string tension on a non responsive yoyo?

I have a dv888 and I was wondering how to make my string tension less. I mean I know you can do the ufo but I thought that was with responsive yoyos only? I just dont like changing strings a ton to do suicides. thanks for answering my endless questions lol.
